To have this elbow bending mod actually work for anything you first need to do the part 1 of the elbow mod. You can find it here:
Now, to take further advantage of the elbow articulation mod cut a bit of the piece with the tail on Talon. Like I said in the part 1 of the mod, that plate, which Tigris also has, limits how much the elbow can bent after the mod.
Used a dremel to remove part of the plastic fast and easy.
Make a continuation of the circle like in the pic below.
Now the piece slides perfectly on the rail I created locking in place when I it moves. I don’t even have to move it, it just slides by itself when I bend the elbow.
So with all the mods I can get this articulation out of Talon (Tigris has not been modified in any way).
Really happy with the results!
